Wind it at each end, clear of the down plate. The aim is to prevent metal-to-metal contact, which a rope at either end will do.
Telling me something I hadn’t grasped. So the rope is to ensure the weedhatch cover doesn’t vibrate against any of the other metal of the boat? So why would it not vibrate in deeper water?

If it is osculating it will be going the other way, the rope was to cushion it against the front and back edge of the weed hatch, so wound at 90° to what you have
Can’t wind it that way as their a down plate going that way

Back on the Oxford Canal, immediately the noise returned. I am convinced it is turbulence , cavitation noise. As suggested I wrapped rope around the bottom plate as shown but that made no difference. Also have released the vacuum by nicking the seal but to little effect. There is no noise at 1000 revs but put it higher and back it comes. Go into deeper water and it greatly reduces. I’ve been asked for some measurements,
top plate to bottom plate is 30 cm
tip of prop is 18 cm below water line
Prop is 8cm from bottom plate
any more suggestions please

The moorings on the river just above Osney lock, from there to Osney Bridge, are excellent. It is still only a few minutes walk into the centre of town from there; also there is a big supermarket a few minutes away in the other direction (and a launderette). If they are full, you can also moor on the river immediately beyond the Sheepwash junction.
That’s very useful, tx

Tx Tony. If they r full assume I’ll go north on canal, any moorings along there? I’ve committed when I come thru the channel I think?

Advice please. On Thames in Abingdon and coming up stream and onto Oxford Canal. Want to spend a couple of days in Oxford and hope to find a quiet secure, safe mooring with easy access to Oxford centre. Should I stay on river to Dukes cut or onto OC as soon as. Any recommendations Re moorings please.

I'm in Maidenhead, and would thoroughly recommend my local, The Boathouse at Boulters Lock. Very good gastropubby type food, middling prices and pontoon mooring.
The Waterside is indeed fantastic, with Michelin stars and would be great it you wanted a very special formal dinner. Not sure it'd accommodate a narrowboat on it's mooring though but worth asking ahead if you fancy it. An alternative 'Roux' offering is located by Maidenhead Bridge at more Brasserie prices.
Oakley Court is good for a hotel. Great location and a fantastic building which starred as the house in Rocky Horror and the School in St Trinians!
French Horn in Sonning is superb for very traditional French Cuisine at a high-ish price point, but is on a backwater and may be inaccessible depending on your boat and/or stream conditions. There's mooring in Sonning a five minute walk away though. Also the Great House in Sonning which is good, or the pub, The Bull which George Clooney tried to buy so I guess is OK.
The Bounty is quirky but not a gastronomic destination unless you enjoy the 'prison chic' of having your (generally fried)meal served on a metal plate.
Spade Oak is good but don't bank on there being a mooring and if there isn't there's no alternative within a reasonable walk of the place. The King's Arms in Cookham as previously mentioned is excellent and the same 'mini chain' as the Spade Oak. Many other options in Cookham if you fancy a short stroll. The restauranty White Oak is very good indeed, as is the pubby Old Swan Uppers.
Marlow's got many options, the best IMO being Tom Kerridges 'The Coach'. By the bridge and with potential moorings is the Compleat Angler with a great Michelin starred Indian restaurant.
Henley also has many offerings as mentioned.
Reading's not really the best for a 'special' experience IMO.
Hope this helps!
Bon Appetite
That’s very useful, tx for taking time

Are any of these edges shiny, mine where where they were vibrating on the shoot. wrapping the cord round isolated them so the noise changed
Just checked and no shiny edges

Do you have a down stand plate on the weed hatch lid? If so, depending on exactly where you position the lid when you put it back, it might or might not vibrate against the weed hatch trunk.
Not sure what you mean by down plate, photos attached
12 hours ago, ditchcrawler said:On ours I actually bound the bottom plate with cord to prove where it was coming from. When I mentioned it to some one they said why didn't you just invert the lid to try it.
So simply wrapping cord around bottom plate…..how does that prove where it’s coming from? Tx

I would be tempted to just make a tiny nick in the weedhatch seal to break the vacuum. Not likely to sink the boat unless you do something very odd. Might make some difference but I think you are right, turbulence sounds like the reason. I suppose bolting a rectangle of 3/4" ply to the bottom plate might damp the resonance or frequency of the vibrations. The fact that it stopped after you had left the boat sounds like weed or mussels had attached to the plate. You could try sticking some mussels on it in varying patterns to get the optimum effect.
Confused Re mussels? If it helps, when I’ve been on the Thames been at time 1400 revs, there is a noise which is acceptable and sounds much like the problem noise but much quieter. This is one of the reasons I think there’s a turbulence issue

Any dangers of trying the nick idea?

Would welcome any more views…update. I’ve been out on it now for 4 weeks, down the GU the noise was on and off but when I got on the Thames…no noise. I am firmly of the opinion that it’s a turbulence, cavitation noise exacerbated with shallow water. There have been some suggestion that it’s to do with plates etc in the weedhatch causing problems, I agree with this. There is still a very strong vacuum when I try and remove weedhatch..any connection? Anything I could try . Tx to all again?
-
Many tx for all the suggestions, going thru them on Tripadvisor. Am now 2 days in Windsor, then heading slowly upstream on Friday, no hurry.

Got to be The Waterside inn at Bray.
Tx, will certainly take a look, website looks impressive. Does it have own moorings?
-
Now in Staines and going west on Thames, need a quality pub/restaurant, preferably with moorings, to celebrate a special day. All suggestions greatly received. Reading web reviews we have found can be most misleading

I find a long 3" or so cross head wood screw does the job. Cross head so when the screwdriver slips it won't stab you.
Screw into the old packing and pull out with pliers.
Hi Tony, so you would recommend removing all the old stuff?
-
About to renew the packing on my stern gland. Am told best to remove all of the old and need a special removal tool.
so….is it necessary to take all the old out and
do I need the removal tool?

Have you tried looking at inline filters website? They have a very good equivalents finder.
If it is not there as an equivalent, measure the main dimensions including the thread size/pitch and you can look up an equivalent that way.
You could also try online filters. They have a rep for being helpful.
Vetus are rather good at buying bespoke auxiliary items, and charging the earth for them though. If you cannot find an equivalent it might be cheaper to swap your filter unit out with a Delphi 296 agglomeration filter. Loads on line- just ensure you get one with a metal bowl and drain plug to keep BSS happy.
N
Tried them, no replacement, have to buy from Vetus
-
Tx for that, will think about a change of filter, any ideas which one would suit?
-
There’s a fuel filter already on the Beta 43 engine, is it usual to put a second inline fuel filter in?
-
-
Anyone know where I can get a non vetus element for this filter, they are £37 plus vat for vetus element. Element vetus code is vt33eb
